UNITED YSTATES PATENT OFFICE- JOHN ALBERT BOSCH, OF MARYVILLE, MISSOURI.

CAR-COUPLlNG.

SPECIFICATION forming part of Letters Patent No. 367,586, dated August 2, 1887.

Application filed June 21, 1887. Serial No. 241,968. (No model.)

To all whom it may concern:

Be it known that I, JOHN ALBERT Besen, a citizen of the United States, residing at Maryville, in the county of Nodaway and State of Missouri, have invented certain new and useful Improvements in Gar-Couplings; and I do declare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon,which form a part of this specification.

This invention relates to an automatic car coupling for freight-cars, in which a link is used which can be employed to couple with cars having the ordinary couplings, in which the cars can be uncoupled from either side or from the top if the car is a boxear, and in which the automatic coupling device can be held out of operative position in case it is desired to buff the cars.

The invention ris illustrated in the accompanying drawings, in which- Figure 1 is a side View of a portion of a car provided with the improved coupling. Fig. 2 is a front View of the same. Fig. 3 is a 1ongitudinal sectional view of the draw head. Figs. 4, 5, 6, and 7 are views of partsin detail.

A is the draw-bar, having chambered drawhead B. The draw-bar is a spring draw-bar of usual construction, having a limited longitndinal movement and held normally forward by a spring,'-O. D is the coupling-link, considerably longer than the ordinary link,whieh enters the ehambered draw-head. The drawhead is constructed to receive the usual pin, E,

if necessary.

Journaled across the upper part of the chamber of the draw-head is a shaft, F, and to this shaft is ri gidlysecurcd a downwardly and rearwardly extending coupling plate, G. This coupling-plate is inclined on its forward or outer edge, and swings (with the shaft) between two similarly-inclined stationary guideplates, H H, which direct the incoming end of the coupling-link to the lower part of the ehamber. The couplingplate usually retains its lower-most position,and the incoming link contacting with its inclined face swings the same upward until the solid forward portion of the link passes beyond the inner edge of the plate,

when the plate descends into the slot of the link, thus coupling the ears. The descent of the plate is accelerated and the coupling insured by a spring, I, the location of which will be hereinafter specified. The guide-plates H H also act as guides to the coupling-plate, di' recting it into the slot of the link.

To uncouple the cars, it is only necessary to raise the inner end of the coupling-plate by the rotation of the shaft F. To eiect this rotation froni either side or the top of the car, the shaft is provided with a rigidly-attached rearwardly-extending lever, J, having elongated slot a. J ournaled between suitable cheekpieces, b, on a plate, K, fastened to the top of the car, is a three-armed lever, L, having two horizontal arms, c d, and a vertical arm, e. One ofthe horizontal arms, c, extends over the edge of the car, and has an elongated slot, f, therein.

` M is a vertical connectingrod having elongated slots g g in each end, which rod extends through a guide-aperture in the top plate, Ii. The lower slot in rod M embraces the lever J, and `a pin, h., carried by the rod, passes through the slot a in lever J. In an exactlysimilar manner the upper end of the rod M is connected to the outer arm, c, of lever L. The slots c and f are essential, in order to prevent the parts being injured by the movement of the draw-bar. The ends of the arms d and e of lever L are shaped to adapt them to be used asafoot-piece and handle, respectively, so that they may be operated either by foot or hand. The movement of the lever L in the direction of arrow l raises the rod M and the lever J, thus rotating shaftF andlifting the coupling-plate, whereby the cars are uncouplcd.

The several parts are caused to automatically assume their position for coupling the cars by the spring I, which is a coiled spring fastened beneath the Vcar and having an arm, '13, which is held in an aperture, j, in the rod, M, through which it slides freely during the movement of the several parts. The top plate, K,

which is of metal, is bent upwardly to form a guide-arch, N, which is provided with slots m on, through which the arms of the lever L pass. In case it is desired to buff the cars,the coupmust be held up out of the way. To a swinging catch, O, is pivoted to ling-plate effect this,

IOO

` R, which extends through a slot, n, in the rod M. The arm R has a slot, s, through which passes a pin, t, carried by the rod M. Move. ment of either lever Q in the direction of arrow 2 raises arm R and rod M, thus uncoupling the car.

At each end the shaft l? has a fixed horizontal arm, S, alongside the car and running beneath the guide w. This arm, when depressed by the movement of lever Q, is adapted to be engaged by a swinging catch, which holds the same depressed, so that the cars may be buffed when so desired.

I claim as my inventionl. The ehambered draw-head and the shaft naled therein, and the coupling-plate carried 4o thereby, in combination with the lever J, the rod M, and the shaft P, having levers Q Q and horizontal arm R, con necting with rod M, catch-Y arms S S on said shaft, and catches T T, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN ALBERT BOSCH.
